Yes, this is correct. The serialized part is the tube. That is what is in the NFATR. The problem is that the ATF sees anything "extra" as in baffles and certain types of extensions are regarded as "silencers" themselves.

"Muffler or silencer
Any device for silencing, muffling, or diminishing the report of a portable
firearm, including any combination of parts, designed or redesigned, and intended for the use in assembling or fabricating a firearm silencer or firearm muffler, and any part intended only for use in such assembly or fabrication. "
This exists in this manner because at one time you could open shotgun news and on one page buy tubes with threaded endcaps, then on another page from a "different" seller buy the baffles that happen to fit that tube. A long while back at gunshows you could see sellers selling baffles and tubes on the same table or tables very near each other. Neither of which was considered a silencer at the time. It took prosecutions of constructive intent for the ATF to be able to get it changed. Basically, if you have parts A and B you intend to make a silencer. If you have a short silencer and thread on a part that makes it longer and or happens to contain baffles, you have made a NEW silencer.
There are some exceptions to some things like Nielsen devices, boosters, and thread adaptors.
How a SOT can work on Suppressors is covered here:

"Q: May a repair change the dimensions or caliber of a silencer?
If alterations to a silencer would increase the overall length or change the diameter or caliber of a silencer, this is the making of a new silencer, as opposed to a repair. The new silencer must be registered and transferred in accordance with the NFA and the GCA. Alterations to a registered silencer that result in a minimal reduction in the overall length for purposes of rethreading are permissible as repairs. However, the reduction in length may not result in the removal, obliteration, or alteration of the existing serial number, as this would violate 18 U.S.C. § 922(k). If such a repair is necessary, the damaged silencer should be destroyed or returned to the registrant. If it is destroyed, destruction should be reported to the NFA Branch. Any replacement silencer must be registered and transferred in accordance with the NFA and the GCA. See also “May a Federal Firearms Licensee repair a silencer by replacing worn or damaged components?” and “May the outer tube of a registered silencer be repaired due to damage? If so, may the repair be done by someone other than the original manufacturer?” for further information on repairs."
Because of all this, I cant see how you can buy a component shorter than the full length device and simply purchase and or add parts that further diminish the report and add length, especially without new tax stamps.
Or Silencerco got some kind of ATF FTB letter that negates them from all of this. That happens sometimes too. If they do not explain this part soon, I will just ask them.
